ven for Fla/r2 DIESTELKAMP ,lffor/zegs Patented Aug. 20, 1940 warren stares FATENT @FFEQE Application December 24, 1937, Serial No. 181,503. Renewed May 3, 1940. In Germany December 20 Claims. (Cl. 16-147) This invention relates to the construction of side fittings, more particularly for window casements, which are rotatable at will about avertical and a horizontal axis. Windows of this type are describecbfor example, in the German Patent No. 646,815 in which the upper'side fitting, which also fulfils the function of the upper hinge, is constructed as a solid adjusting bar of circular cross section on which slides a sleeve united with the window casement through a pin connection. If the window casement is to be rotated about its vertical axis the lower end of the adjusting bar, which can oscillate about a horizontal axis extending parallel to the plane of the window, is fixed by means of a rotary bolt and the sleeve fixed to the window casement serves as a hinge. This known device has the disadvantage that the surface of the adjusting bar cannot be provided with a coat of paint and that as it is generally oiled as a protection against rust and to lubricate the sleeve it generally has a dark and unsightly appearance and leads to soiling of the hands and curtains.

The subject of the invention is an improvement in these known windows which avoids the disadvantages mentioned above and gives a substantially improved construction which is inconspicuous, has an appearance similar to that of a hinge and by simplifying the individual parts provides a not inconsiderable reduction in costs compared with the known device serving the same purpose so that the new fittings cost only slightly more than those of a normal window. Fittings of this kind are equally applicable to wood and metal windows.

Reference will now be made to the accompartying drawings illustrating several examples of construction according to the invention and in which:

Figure 9 is a view of the joint in Figure 8 after removal of the connecting ball.

A window casement which is to be rotatable at will about a vertical or horizontal axis requires two rotary pivots for each of the axes of. rotation lying at right angles to each other, that is, ,four joints or hinges altogether. Generally two of these rotary pivots are combined in one fitting, the so-called corner hinge, so that altogether three separate fittings are sufilcient for a bottom and side hung window casement. This corner hinge allows two rotations at right angles to each other.

The hinge required in addition to the corner hinge for the horizontal axis of rotation consists, in the example of construction illustrated, of a horizontal hinge strip disposed underneath the Window casement, of which one-socket 4 is provided at the lower edge of the casement frame 2 whilst the second socket 3 forming this hinge strip is fixed to the window frame I. Within the socket 3 the bolt 5 providing the horizontal axis of rotation is limited as regards movement by means of its end 6 bent over at right angles to form a handle whereby the two hinge strip parts can be coupled and uncoupled. This fitting, which does not form the subject of the invention, is illustrated in Figure '2.

The corner hinge required for both directions of rotation is illustrated in Figures 1 and 2. The pivot pin 9 is' connected by means of the pin joint It to the plate I, sunk into the window frame I and secured thereto by screws, and serves as a hinge pin for the hinge strip H fixed to the window casement 2. 1

The most important component of a window casement which is to be rotatable at will about a horizontal and vertical axis isthe upper side fitting whichsimultaneously serves as the upper vertical hingeand as the retaining or adjusting device for the window casement opened out about its horizontal axis. According to the invention this holding or adjusting bar is formed as-a slotted hollow bar which is secured at its upper end insuch a way that it can be rotated about a vertical axis and can also be swung forwards about a horizontal axis extending parallel to the plane of the window.

These conditions can be fulfilled with the fitting according to the invention. The vertically disposed socket i3 is screwed to the window frame I by means of the plate [2 (see Figures 1 and 2). The hinge pin [4 to the lower end of which the adjusting bar l6, consisting of a slotted tube, is connected by means of the horizontal pin joint I5, is rotatably supported in the socket I3. The hollow adjusting bar Hi can have a round, rectangular or similar profile (see Figures 6 and 7).

Inside there is disposed the sliding block ll corresponding to the profile of bar Hi. The block I! by means of the pin l9 sliding in the slot I8 is firmly connected with the bracket 20 secured to the casement frame 2. The'sliding block I! is shaped as a rotational .body, co-axial with the fixing bolt, whose axial section corresponds to the crosssectional shape of the adjusting bar l6;

Two examples of this are shown on an enlarged scale in Figures 6 and '7. If the adjusting bar l6 has a cylindrical cross section the sliding block is constructed as a ball I! witha neck 19. If the adjusting bar is a tube l6 (Figure 7)- of rectangular cross section the sliding block is shaped as a cylinder l7 co-axial with the neck I9.

For the rotation of the window casement about the vertical axis where the adjusting bar l6 has to take over the function of the upper hinge, it is fixed in the vertical position according to the invention by means of a locking device 23, preferably maintained in its position of rest by the action of a spring, acting as a rotary pin, axial bearing, bush or the like and which is fixed to the window frame I vertically below the upper rotary hinge, 15 of the adjusting bar [6 at a distance corresponding to the length of the adjusting bar 16.

The section shown in Figure 3 shows an example of construction of the lower axial point of the adjusting bar'lfi in which the securing member fixed to the window frame I is constructed as an axial bearing, bush'or the like, in which is inserted an axial pin 22 fixed tothe lower end of the adjusting bar l6 and lying in its longitudinal axis and rotatably supportedtherein.

The lower end of the hollow adjusting bar I6 is closed with a closure member 2| fitting inside and which has a downwardly projecting and backwardly chamfered axial pin 22 of circular cross section (see Figures 1 to 3). This axial pin 22 co-operates with the locking device 23 (Figures 1 and 2) which is shown in, longitudinal section in Figure 3 on an enlarged scale at right angles to the plane of the window frame I. The vertically disposed socket 25 is screwed to the window frame I by means of the plate 24. The securing bolt 26 under the action of the spring 2'! is freely supported in the socket 25 and secured through a gripping ring 28 or a pin or like member. At the constricted lower end 29 of the bolt 26 the draw chain 3| with a handle 32 is fixed in the eye 30, this being particularly'necessary for unbolting if the locking device situated comparatively high up.

At its upper end the locking bolt 26 has a cup shaped or cylindrical recess 33 allowing axial rotation of the pin 22. In order to facilitate the engagement of the axial pin 22 in the recess 33 particularly whenthe adjusting bar I6, whose lateral guiding is effected substantially through the sliding block IT, has a slight amount of lateral play, the front chamfered surface 34 of the locking bolt 26 is widened towards the outside in deltoid shape, whereby the lateral flanks 35 form a suitable guide for the axial pin 22 so that on downward movement of the adjusting bar I6 the said pin automatically goes into the recess 33 of the locking bolt 26 serving as a rotary bearing and which snaps back under spring action. The surface of the bolt with the opening 33 and the chamfer 34 is shown in plan in Figure 5.

There is no departure from the principle of the invention if, reversing the arrangement illustrated here, the axial pin 22 is provided on the locking bolt 26 and the central aperture with the deltoid chamfer is provided in the closure part 2| of the adjusting bar l6, as illustrated in section in Figure 4.

The upper rotary connection of the adjusting bar it can also be constructed as a ball pivot formed in such away that in addition to rotation about a vertical axis it also allows swinging about a horizontal axis in a plane at right angles to the window frame. For this purpose the ball socket 31, illustrated in Figure 8 in longitudinal section and in Figure 9 in plan after removal of the ball pivot, and secured to the window frame I by a screw 36, is provided with a vertical slot 38 which permits the aforesaid oscillation of the neck 39 of the ball 40 which is fixed on the upper end of the hollow adjusting bar I6.
